The working principle of the car heater is that the radiator in the heater is connected to the engine circulating water through the inlet/outlet pipeline. The water valve is a switch: when the water valve is opened, the water circuit Turned on, the engine circulating water enters the radiator, and the fan blows the heat into the cab; on the contrary, the water valve is closed and the warm air does not work.

The opening and closing of the water valve can generally be divided into two types: electronic control and manual control. Electronic control: control panel, wiring, steering gear and other components; manual control is basically realized by turning a knob (usually controlled by drawing), and the specific internal structure is similar to a faucet , The spool rotation determines the water flow in the pipeline.
